Abstract (en)
[origin: EP2749537A1] To obtain a precursor for a positive electrode active material capable of improving cell characteristics of a nonaqueous electrolytic secondary cell. Upon producing a nickel composite hydroxide having a composition represented by Ni 1-x-y-z Co x Mn y M z (OH) 2+A (where 0 ‰¤ x ‰¤ 0.35, 0 ‰¤ y ‰¤ 0.35, 0‰¤z‰¤0.1, 0 <x+y, 0 <x+y+z‰¤0.7, 0 ‰¤A‰¤0.5, with M being at least one kind of additive element selected from the group consisting of V, Mg, Al, Ti, Mo, Nb, Zr and W), a plate-shaped crystal core is generated by allowing a crystal core generating aqueous solution containing cobalt and/or manganese to have a pH value of 7.5 to 11.1 at a standard liquid temperature of 25°C, and slurry for the particle growth containing the plate-shaped crystal core is adjusted to have a pH value of 10.5 to 12.5 at a standard liquid temperature of 25°C,while a mixed aqueous solution containing a metal compound containing at least nickel is being supplied thereto, so that the plate-shaped crystal core is grown as particles.
